Senior Analog Circuit Design Engineer

Job Summary:

onsemi is seeking a self-driven and motivated professional to join ISG Technology group - analog design team. 
As a Sr. analog design engineer, you will have the opportunity to be a part of a team, leading imaging projects and supporting onsemi ISG most advanced technologies. 
you will participate in a broad range of design activities in a highly dynamic working environment, covering all product life cycle - from Idea to design, Silicon validation and product integration.

Performance Objectives

• Lead the design of advanced analog and mixed‑signal circuits for next‑generation sensing technologies, including:
  • CMOS image sensors.
  • Time‑of‑flight (ToF) systems.
  • SWIR and other non‑visible‑spectrum imagers.
  • Novel or exotic sensor architectures.
• Own critical analog blocks such as:
  • Low‑noise front‑ends and charge‑domain circuits.
  • High‑speed ADCs (SAR, pipeline, custom architectures).
  • Precision bias/reference circuits.
  • High‑bandwidth readout chains.
  • Pixel‑level analog circuitry tailored to specialized sensing modalities.
     

1. Perform transistor‑level design, simulation, optimization, and corner/Monte‑Carlo analysis.
2. Collaborate closely with pixel, digital, process, and system engineering teams to co‑optimize performance.
3. Lead silicon bring‑up, debug, and characterization; analyze lab data and drive design improvements.
4. Contribute to architecture discussions and long‑term technology roadmaps.
5. Mentor junior engineers and strengthen design methodologies across the group.

Requirements:

• B.Sc. or M.Sc. in Electrical Engineering (Ph.D. a plus).
• 5 years of experience in analog/mixed‑signal IC design.
• Proven track record of delivering successful silicon in production or advanced prototypes.
• Deep understanding of analog fundamentals: noise, matching, linearity, stability, device physics.
• Strong experience with Cadence Virtuoso, Spectre, and advanced simulation methodologies.
• Demonstrated ability to debug silicon and correlate measurements with simulations.
• Strong communication and collaboration skills.

Preferred Qualifications

• Experience with image sensors, ToF systems, SWIR imagers, or other advanced sensing technologies.
• Expertise in low‑noise design, high‑speed ADCs, or precision analog circuits.
• Familiarity with semiconductor process variation, reliability, and yield optimization.
• Hands‑on lab experience with characterization equipment.
• Experience leading technical projects or mentoring engineers.
